Question 1013705: when sally went bowling, her scores were 108, 72, and 95. if she bowls a 4th game, what will her score need to be to give her an average of 91?

To average 91 for four games, she will need a total of 4(91) = 364.
She has already scored 108+72+95 = 275.
Thus she will need 364 - 275 = 89 on her last game to average 91.
